ZPL Control Setup

Control Prefix - The control prefix sets the character the printer will look for to determine a ZPL Control Command. By Default the value is "~" tilde (7E Hex). You should not change this value unless you are expecting to use a tilde "~" as part of your data stream. 

Format Prefix - The Format Prefix is the character the printer will look for to determine a ZPL Command. By Default the value is "^" caret (5E Hex). You should not change this value unless you are expecting to use a caret "^" as part of your data stream or for example you are using an IBM OS that does not have a caret as part of the character set.  

Delimiter Char - The Delimiter is the character the printer looks to for command separator values comma "," and is rarely changed.

ZPL Mode - This value can be set to ZPL or ZPLII. There is little difference in the printer response and keeping the value defaulted at ZPL II is the most common setting.
